SETTLlNG-TANK.

SPECIFIGATION forming part of Letters Patent No. 251,717, dated January 3, 1852. Application filed ,l'une 25, 1881. (No model.)

To all whom it may concern Be it known that I, ALFRED E. JoNEs, of Newark, in the State of New Jersey, have invented a new Settling-Tank, of which the following is a specification, reference being had to the drawings accompanying the same.

My invention consists in the combination of partitions, hereinafter described, with a tank, in the bottom of which are openings between each partition, whereby the sediment may be drawn off and each opening or slot supplied with a revolving disk, whereby the opening may be closed or exposed, as hereinafter described.

My invention is more especially adapted for use in mixing colors in potters uses, refining clay, and recovering dyes when precipitating agents are employed, and when it is desired to tants.

In an application simultaneously herewith made I use this settler for the purpose of separating the heavier, particles of ore, 8210., from the lighter weighted gold, and the gold floatingin the liquid is drawn off and subsequently treated as therein stated.

I will now describe my settling-tank.

Figure 1 is plan view of my tank settler, and Fig. 2 is a section of the same.

A is the tank proper, and is of the desired size.

B B B B B B are partitions situated'at right angles to the bottom of the tank, which bottom is a flat plane surface. These uprights are so constructed at about their center as to of the partition B as to shut off all communication or access to the bottom of the tank, but allowing all sediments or liquids in the box to flow or fall down upon them.

y 0 0 o 0 0 o o are openings or holes in the bottom of the tank, and are constantly left open.

Suppose I Wish to separate the heavier part of the precious metal from sand-tailings, &c. The ore or sand-tailings coming from a common pug-mill or quartz-crusher is led, with sufficient water, through the pipe a into the tank A. As soon as the first partition is full the second becomes filled, and so on till the whole tank is filled up. Then being-allowed to stand, the disk remaining as shown in the drawings, the heavier particles all settle to the bottom through the opening where the disk is cut away. When sufficiently settled the liquid, with its float, is drawn off through the pipe to into a receptacle. Now turn the disks over so that their curved sides cover the entire distance between the uprights or separators B B, and it will readily be seen that the sedi-. ment will pass through orcan be pulled through the openings into the drawer L and put again into the pug-mill or crusher. All this is done without interfering with the operation of the machine. a

It will readily be seen that this settler can be employed in precipitating dyes, 850., also for potters uses.

What I claim, and desire to secure by Letters Patent, is

The tank A, provided atits bottom with openings o, and having partitions B, said partitions havinginclined and curved portions, as shown, in combination with the segmental disks 0, substantially as described, and for the purpose specified.
